Search help in dynpro

Question

Hi to all,
In my application I have a field with a search help.
I want that this field only can be modified using a search help and this field can't be modified directly writing in this field.
Is similar to transaction se63 - Translation - Abap objects - Short texts - OTR - Source language
I have created an example with the field SFLIGHT_T-CARRID but this field can be modified with search help and directly, or this field can't be modified.
How can i solve this problem?
Thanks a lot.

Hi,
In my application I have done the following:
-> Screen painter (layout):
Name: SCARR-CARRID
Input Field: not marked
Output Field: marked
Possible entries: marked
Possible entries keys: 2
-> Flow logic:
PROCESS BEFORE OUTPUT.
  MODULE IMPORT_DATA_0001.
PROCESS AFTER INPUT.
  MODULE EXPORT_DATA_0001.
PROCESS ON VALUE-REQUEST.
FIELD SCARR-CARRID MODULE listbox.
PROCESS ON HELP-REQUEST.
MODULE listbox INPUT.
  TYPES:
       BEGIN OF VRM_VALUE,
         KEY(40) TYPE C,
         TEXT(80) TYPE C,
       END OF VRM_VALUE,
       VRM_VALUES TYPE VRM_VALUE OCCURS 0,
       VRM_ID TYPE VRM_VALUE-TEXT,
       VRM_IDS TYPE VRM_ID OCCURS 0.
  DATA: name TYPE vrm_id,
        list TYPE vrm_values,
        value LIKE LINE OF list.
  CHECK list[] IS INITIAL.
  name = 'SCARR-CARRID'.
  SELECT carrid CARRNAME FROM SCARR
    INTO (value-key,value-text).
    APPEND value TO list.
  ENDSELECT.
  SORT list BY text.
  CALL FUNCTION 'VRM_SET_VALUES'
  EXPORTING
    id = name
    values = list.
ENDMODULE. " LISTBOX INPUT
But this don't fix my problem, I can see the diferent values with match code but I can't choose a value.
Can somebody help me again?
Thanks a lot.
